Aligning records for visual comparison

ABSTRACT

Various embodiments of systems and methods for aligning records for visual comparison are described herein. In one aspect, the method includes identifying a plurality of records. A reference record is selected from the plurality of records. One or more non-reference record is merged into the reference record to generate a merged reference record. The merged reference record includes one or more fields missing in the reference record. The missing fields are included as blank fields from the non-reference records. The merged reference record is merged into a non-reference record to generate the merged non-reference record. The merged non-reference record includes fields missing in the non-reference record. Missing fields are included as blank fields. The merged records are displayed on a user interface in a card view.

BACKGROUND

A record is a data structure for storing information related to an entity. The record comprises various data related to the entity. For example, the record for a customer may comprise data, e.g., a name of the customer, an official address of the customer, a residential address of the customer, a contact number of the customer, etc. It may be required to compare multiple records. For example, it may be required to compare the record of a customer ‘xyz’ and a customer ‘pqr.’ A visual comparison may be preferable or needed.

However, it may be difficult to compare the records if the records are placed one on the top of another with data of the records being displayed horizontally. Typically, if the data of the records are displayed horizontally and the records include many data then a user may need to scroll back-and-forth or up-and-down across the records to compare various data which might be inconvenient and time consuming. The records may be placed side-by-side in a vertical arrangement (e.g., in a card view) to obviate the above-mentioned problems. However, even if the records are placed side-by-side, like data of the records may not be in alignment. For example, the ‘residential address’ of the customer ‘xyz’ and the ‘residential address’ of the customer ‘pqr’ may not be in alignment or may not line up in a same row.

FIG. 1 illustrates some examples that may cause misalignment of the like data of the records, e.g., the misalignment of the like data of a record 101 (i.e., left card) and a record 102 (i.e., right card). Consider three cases.

Case 1: The record 101 includes a first name 101A and a last name 101C of the customer, while the record 102 includes a first name 102A, a middle name 102B, and a last name 102C of the customer. Therefore, the record 102 includes an additional field 102B (e.g., middle name) that is missing in the record 101 and it causes misalignment. Typically, due to misalignment the data (rows) of the record 101 and the corresponding data of the record 102 do not line up. For example, a ‘REGION’ data 101R and a ‘MASKED’ data 101M of the record 101 and the corresponding ‘REGION’ data 102R and the ‘MASKED’ data 102M of the record 102 do not line up in the same TOW.

Case 2: The record 101 may include two addresses, e.g., ADDRESS 1 and ADDRESS 2 whereas the record 102 may only include one address, e.g., ADDRESS 1 that can also cause misalignment.

Case 3: The data, e.g., ADDRESS 1 of the record 102 may include two levels of hierarchy (102H1 and 102H2) compared to the corresponding ADDRESS 1 of the record 101 that may also cause misalignment.

Misalignment may cause inconvenience when comparing the records as the like data of the records do not line up in the same row. Further, comparing the misaligned records (e.g., the record 101 and 102) may be time consuming.

SUMMARY OF THE INVENTION

Various embodiments of systems and methods for aligning records for visual comparison are described herein. In one aspect, the method executed by one or more computers in a network of computers includes identifying a plurality of records, selecting a reference record from the plurality of records, and merging one or more non-reference record into the reference record to generate a merged reference record. The merged reference record includes one or more fields that are missing in the reference record. The missing fields are included as blank fields from the one or more non-reference records. The merged reference record is merged into a non-reference record to generate a merged non-reference record. The merged non-reference record includes one or more fields missing in the non-reference record. The fields are included as blank fields from the merged reference record. A position or order of an included blank field is determined based upon the corresponding order or position of the field in the merged reference record. The merged reference record and the merged non-reference records are, therefore, aligned relative to each other. The merged records are displayed on a user interface in a card view. Displaying merged records (i.e., aligned records) in the card view enable a user to efficiently and conveniently compare the merged records.

DETAILED DESCRIPTION

Embodiments of techniques for aligning records for visual comparison are described herein. In the following description, numerous specific details are set forth to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.

Reference throughout this specification to “one embodiment”, “this embodiment” and similar phrases, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of these phrases in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

FIG. 2 is a flowchart illustrating a method for aligning records for visual comparison, according to one embodiment. A plurality of records is identified at step 201. A reference record is selected from the plurality of records at step 202. In one embodiment, the reference record is selected randomly. In another embodiment, the reference record is selected based upon a predefined rule. In yet another embodiment, the reference record is selected based upon a user's input. One or more non-reference record is merged into the reference record to generate a merged reference record at step 203. In one embodiment, each non-reference record is merged into the reference record to generate the merged reference record. The merged reference record includes one or more fields missing in the reference record. In one embodiment, the fields of the reference record are compared to the fields of the non-reference records to determine the fields missing in the reference record. The missing fields are included into the merged reference record. The missing fields are included as blank fields. The merged reference record, therefore, is a superset that includes all the fields of all the records. The merged reference record is merged into each non-reference record to generate respective merged non-reference record at step 204. The merged non-reference records include fields missing in the respective non-reference records. The fields are included from the merged reference record as blank fields. In one embodiment, a position of an included blank field is determined based upon the position of the corresponding field in the merged reference record. The merged reference record and the merged non-reference records are aligned relative to each other. The merged records are displayed on a user interface (UI) in a card view at step 205. In the card view, the records are displayed side-by-side in a vertical arrangement.

FIG. 3 illustrates one embodiment of a system 300 including a records aligning module 320 to align a plurality of records 310(1-N). The records 310(1-N) are identified by the records aligning module 320. The records aligning module 320 selects a record 310(1) as a reference record. The reference record 310(1) and non-reference records 310(2-N) are passed to a merge algorithm 330. The merge algorithm 330 merges one or more non-reference record 310(2-N) into the reference record 310(1) to generate a merged reference record 340(1). The merged reference record 340(1) may include one or more fields missing in the reference record 310(1). The fields are included from one or more non-reference records 310(2-N). In one embodiment, the fields of the reference record 310(1) are compared to the fields of each of the non-reference records 310(2-N) to determine the fields missing in the reference record 310(1). The missing fields are included into the reference record 310(1) from the corresponding one or more non-reference records 310(2-N) to generate the merged reference record 340(1). The missing fields are included as blank fields. The merged reference record 340(1) is, therefore, a superset that includes all the fields of all the records 310(1-N). The merged reference record 340(1) is merged into each of the non-reference record 310(2-N) to generate respective merged non-reference records 340(2-N). In one embodiment, the fields missing in the non-reference records 310(2-N) are determined. The missing fields are included into the corresponding non-reference records 310(2-N) to generate respective merged non-reference records 340(2-N). The fields are included from the merged reference record 340(1) as blank fields in positions where the fields are missing. In one embodiment, a position of an included blank field is determined based upon the position of the corresponding field in the merged reference record 340(1). Each merged record 340(1-N) include all the fields of all the records 310(1-N) and are aligned relative to each other. The merged records 340(1-N) are displayed on a user interface (UI) 350 in a card view 360. In the card view 360 the merged records 340(1-N) are positioned side-by-side in a vertical arrangement to enable efficient visual comparison.

A visual comparison task (e.g., match review task) may be assigned to a user. Typically, the user may require to match or compare the plurality of records 310(1-N). The records 310(1-N) may be misaligned. The misaligned records 310(1-N) are required to be aligned so that they can be easily compared. For example, the records 310(1-N) are required to be aligned such that like fields (data) of the records 310(1-N) line up in a same row.

The records 310(1-N) include various fields. For example, the record 310(1) for a ‘customer’ may include fields, e.g., a first name, a middle name, a last name, a contact number, etc. The like fields of the records 310(1-N) are required to be compared. For example, the fields ‘first name,’ middle name,' and ‘last name’ of the record 310(1) are required to be compared with the corresponding fields ‘first name,’ ‘middle name,’ and ‘last name’ of the record 310(2). Typically, the fields of the records 310(1-N) are required to be aligned properly so that the like fields of the records 310(1-N) line up in a same row and the records 310(1-N) can be easily compared.

The records 310(1-N) may be identified by the records aligning module 320. The records aligning module 320 aligns the records 310(1-N) relative to each other. For aligning the records 310(1-N), the records aligning module 320 selects the reference record 310(1). In one embodiment, the reference record 310(1) is randomly selected. In another embodiment, the reference record 310(1) is selected based upon a predefined rule. For example, the predefined rule may be: “a first record from the plurality of records has to be selected as the reference record.” Based upon the predefined rule the first record 310(1) may be selected as the reference record. In yet another embodiment, a master record is selected as the reference record. The master record may be the record selected by the user from the records 310(1-N). For example, the user may select the record 310(1) as the master record. The master record 310(1) may be selected as the reference record. Once the reference record 310(1) is selected, the records 310(1-N) may be passed to the merge algorithm 330.

In one embodiment, the merge algorithm 330 is a separate entity communicatively coupled to the records aligning module 320. In another embodiment, the merge algorithm 330 is a part of the records aligning module 320, as illustrated in FIG. 3. The merge algorithm 330 receives the records 310(1-N). The merge algorithm 330 identifies the reference record 310(1). The merge algorithm 330 merges the one or more non-reference records 310(2-N) into the reference record 310(1) to generate the merged reference record 340(1). In one embodiment, the merge algorithm 330 merges each non-reference records 310(2-N) into the reference record 310(1) to generate the merged reference record 340(1).

The merged reference record 340(1) includes the one or more fields missing in the reference record 310(1). The one or more missing fields are included from the one or more non-reference records 310(2-N). The fields are included as blank fields. In one embodiment, the fields of the reference record 310(1) are compared to the fields of each of the non-reference records 310(2-N) to determine the fields missing in the reference record 310(1). The missing fields are included into the reference record 310(1) to generate the merged reference record 340(1). The merged reference record 340(1), therefore, is the kind of superset that includes all the fields of all the records 310(1-N). In one embodiment, an order or position of the included blank field in the merged reference record 340(1) may be determined based upon a predefined template or a predefined rule. In another embodiment, the order of the included blank field in the merged reference record 340(1) may be determined arbitrary.

Once the merged reference record 340(1) is generated, the merged reference record 340(1) is merged into each non-reference record 310(2-N). When the merged reference record 340(1) is merged into each non-reference record 310(2-N), the respective merged non-reference records 340(2-N) are generated. The merged non-reference records 340(2-N) may include one or more fields missing in the corresponding non-reference records 310(2-N). For example, the merged non-reference record 340(2) may include the one or more fields missing in the non-reference record 310(2). The fields are included as the blank fields in the positions where the fields are missing. Typically, a value of the blank field is blank.

In one embodiment, the fields of each non-reference record 310(2-N) are compared to the fields of the merged reference record 340(1) to determine the one or more fields missing in the one or more non-reference records 310(2-N). The missing fields are included into the merged non-reference records 340(2-N) from the merged reference record 340(1). The fields are included as the blank fields in position where the fields are missing. In one embodiment, the merged reference record 340(1) is used as a template for determining the order or position of the included blank field. The order of the blank field in the merged non-reference records 340(2-N) is determined based upon the order of the corresponding field in the merged reference record 340(1). The merged reference record 340(1) and the merged non-reference records 340(2-N) are aligned relative to each other.

In below exemplary embodiment, the merging operation is illustrated for aligning the two records 310(1-2). The exemplary records 310(1-2) are illustrated below with the record 310(1) as the reference record and the record 310(2) as the non-reference record. The record 310(1) and the record 310(2) are shown below in table 1 and table 2, respectively.

TABLE 2 Name A Contact ID x PAN No. ABC

TABLE 1 Name A Name ID y

The non-reference record 310(2) is merged into the reference record 310(1). As a result of merging, the merged reference record 340(1) is generated as shown in table 3 below:

TABLE 3 Name A Name ID y Contact ID PAN No.

As shown, the merged reference record 340(1) includes the fields ‘contact ID’ and Pan no' that are missing in the reference record 310(1). The missing fields are included into the merged reference record 340(1) from the non-reference record 310(2). The fields are included as the blank fields, i.e., the value of the fields ‘contact ID’ and “Pan no” is blank or empty.

The merged reference record 340(1) is merged into the non-reference record 310(2). As a result of merging, the merged non-reference record 340(2) is generated as represented in table 4 below:

TABLE 4 Name A Name ID Contact ID x PAN No. ABC

As shown, the merged non-reference record 340(2) includes the field ‘name ID’ missing in the non-reference record 310(2). The field is included from the merged reference record 340(1). The field is included as the blank field, i.e., the value of the included field ‘Name ID’ is empty or blank. In one embodiment, the order or position of the included blank field (Name ID) is determined based upon the order or position of that field (Name ID) in the merged reference record 340(1). For example, as the field ‘Name ID’ is a second field of the merged reference record 340(1), therefore, the field ‘Name ID’ (included as blank field in the merged non-reference record 340(2)) is also included as the second field in the merged non-reference record 340(2).

The merged records 340(1-2), i.e., the merged reference record 340(1) (illustrated in below table 1) and the merged non-reference record 340(2) (illustrated in below table 2) are aligned relative to each other such that the like fields line up in the same row, as shown in table 5 and 6 below:

TABLE 6 Name A Name ID Contact ID x PAN No. ABC

TABLE 5 Name A Name ID y Contact ID PAN No.

In one embodiment, the merging operation is performed using an array representation of the records 310(1-N). The array representation of the records 310(1-N) may be generated by an array generating algorithm 400 (FIG. 4). In one embodiment, the array generating algorithm 400 may be a part of the records aligning module 320, as illustrated in FIG. 4. In another embodiment, the array generating algorithm 400 may be a separate entity communicatively coupled to the records aligning module 320.

The records aligning module 320 passes the records 310(1-N) to the array generating algorithm 400. The array generating algorithm 400 traverse each record 310(1-N) to generate an array representation (not shown) of each record 310(1-N). In one embodiment, if the record is hierarchical (e.g., XML records), the array generating algorithm 400 traverse a tree structure of the hierarchical record to generate the array representation of the hierarchical record. The array generating algorithm 400 traverse each node of the tree structure to generate the array representation of the hierarchical record. In one embodiment, the tree structure may be a linked list structure stored in a memory.

The generation of the array representation for an exemplary reference record 310(1) (shown in below table 7) and the exemplary non-reference record 310(2) (shown in below table 8) is described below.

TABLE 8 Customer A First Name xyz1 Middle Name pqr1 Last Name abc1

TABLE 7 Customer A First Name xyz Last Name abc

For generating the array representation of the exemplary record 310(1), the array generating algorithm 400 traverses through a tree structure 500A (FIG. 5) corresponding to the reference record 310(1). Each node (510, 520, 520A, and 520B) of the tree structure 500A is traversed to retrieve the information related to the root node 510 and the one or more descendants (520, 520A, and 520B). As shown in FIG. 5, the tree structure 500A starts with a root node (default node) 510. The customer may be a child node (i.e., the customer node 520) of the root node 510. Similarly, the ‘first name’ and the ‘last name’ may be child nodes 520A and 520B, respectively, of the customer node 520. In one embodiment, the information associated with a node may include one of a name of the node, a number of child nodes associated with the node, a name of a parent node, an occurrence number of the node, properties related to the node representing if the node is hidden or masked, a value of the node, a child index of the node representing if the node is n^(th) child of the parent node (n being a natural number), and one or more comments related to the node.

Based upon the retrieved information of each node (510, 520, 520A, and 520B), the array generating algorithm 400 generates an Array Representation #1 for the record 310(1) as presented below:

public var diffArr1:ArrayCollection = new ArrayCollection([ { name:“root”, childIdx:“0” children:1, parentName:“”, occurNum:“1”, parentName:“”, hidden:“”, masked:“”, value:“” }, { name:“Customer”, childIdx:“1”, children:2, comment:“”, duplicate:“true”, groupNum:“1”, hidden:“”, masked:“”, match_score:“”, parentName: “root”, occurNum:“1”, recordId:“1”, suspect:“false”, value:“” }, { name:“FirstName”, childIdx:“1”, children:0, parentName:“Customer”, occurNum:“1”, value:“xyz” }, { name:“LastName”, childIdx:“2”, children:0, parentName:“Customer”, occurNum:“1”, value:“abc” }, ]);

Each node (510, 520, 520A, and 520B) of the tree structure 500A is recursively visited to enter information related to the ‘root node’ 510 and the descendants nodes (customer node 520, first name node 520A, and last name node 520B) into the Array Representation #1.

In the above shown array representation #1, “Name” indicates the name of the node. For example, the name of the node may be ‘root,’ customer,“first name,” and ‘last name.’

“ChileIdx” represents that the node is n^(th) child of its parent nodes. For example, the ChildIdx of the ‘root’ node 510 is ‘0’ as the ‘root’ node 510 is not a child of any node, i.e., there is no parent node of the ‘root’ node 510. The Childldx of the ‘customer’ node 520 is ‘1’ as the customer is 1^(st) child of its parent node (root node 510). Similarly, the Childldx of the ‘first name’ node 520A is ‘1’ and the Childldx of the ‘last name’ node 520B is ‘2’ as the ‘first name’ node and the ‘last name’ node are 1^(st) and 2^(nd) child of their parent node (customer node 520).

“Children” indicates number of child nodes associated with the node. For example, the children of root node 510 is ‘1’ as the ‘root’ node has one child (customer node 520), the children of customer node 520 is ‘2’ as the ‘customer’ node has two children (first name node 520A and last name node 520B), and the children of ‘first name’ node 520A and the ‘last name’ node 520B is ‘0’ as they both do not have any children.

“Parent Name” represents the name of the parent node. For example, the parent name of the ‘root’ node 510 is empty as the ‘root’ node has no parent. The parent name of the ‘customer’ node 520 is ‘root.’ Similarly, the parent name of the ‘first name’ node 520A and the ‘last name’ node 520B is ‘customer.’

“Value” indicates the value of the node. For example, the value of the ‘root’ node 510 is empty as the root node has no value. Similarly, the value of the ‘first name’ node 520A is ‘xyz’ and the value of the ‘last name’ node 520B is ‘abc.’

“OccurNum” represents the number of occurrence of the node. It represents that the node is occurred n times (n being the natural number). For example, if a record includes three addresses for the customer (i.e., the nodes representing the three addresses would have the same name (address) and share the same parent ‘customer’) then each address node would be assigned an OccurNum 1, 2, and 3, respectively. Typically, the OccurNum is incremented each time the node with a same name and a same parent node is found.

“Comments” shows comments related to the node.

In one embodiment, the descendant node, e.g., the customer node 520 representing the record 310(1) also includes the additional information or attributes related to the record as described in paragraphs 0056-0062.

“Hidden” indicates that the value of the node or field is hidden. The hidden field may be illustrated as blank field. Typically, the value of the hidden field is displayed to only one or more authorized users and is not displayed to other (unauthorized) users. If the field is ‘hidden’ then the value of the field is not displayed.

“Masked” indicates that the value of the node or field is masked (obscured). The value of the masked field is not visible instead some symbols (e.g., *****) may be displayed to represent that it has masked value. For example, the sensitive data such as the value of a credit card number or the user's password may be masked. A number of characters in the symbol illustrating the sensitive data should match the number of characters in the sensitive data. For example, if the sensitive data includes four characters ‘abcd,’ then the symbol illustrating the sensitive data ‘abcd’ should also include four ‘*’ character, i.e., the symbol should be ‘****.’

“RecordId” is an unique identifier of the record. The Recordld uniquely identify the record in a match group. The match group comprises similar records that fulfill certain match criteria. Alternately, the match group comprises the records that are filtered based upon certain match criteria. For example, the match group comprises the records that are filtered based upon the value of the one or more fields. The match criteria may be for filtering all records having ‘first name’ equals to ‘x.’ The match criteria may be specified by the user. The filtered records form the match group.

“GroupNum” represents the group number of the match group to which the record belongs.

“Duplicate” represents if the record is ‘duplicate’ relative to the master record in the match group. The record is considered ‘duplicate’ if the record matches the master record to certain extent based upon the match criteria. The duplicate field may be set to ‘true’ or ‘false.’ If the duplicate is ‘true,’ the record is considered duplicate relative to the master record in the group. If the duplicate is ‘false,’ the record is considered as non-duplicate. The user may set the record as non-duplicate if the user considers that the record does not match the master record to the certain extent based upon the match criteria.

“Match_score” indicates how much the record matches to the master record selected by the user. For example, it may be 60%, 90%, etc.

“Suspect” indicates a Boolean value (YES or NO) that represents if the record is a suspect record or not. The suspect record is a record that has a match score (e.g., match_score) within a predefined range. The suspect record is required to be reviewed by the user.

Similarly, the array generating algorithm 400 traverse the tree structure 500B (FIG. 5) of the non-reference record 310(2) to retrieve information related to each node of the tree structure 500B to generate the below array representation #2 for the record 310(2):

public var diffArr1:ArrayCollection = new ArrayCollection([ { name:“root”, childIdx:“0” children:1, parentName:“”, occurNum:“1”, parentName:“”, hidden:“”, masked:“”, value:“” }, { name:“Customer”, childIdx:“1”, children:3, comment:“”, duplicate: “true”, groupNum:“1”, hidden:“”, masked:“”, match_score:“”, parentName: “root”, occurNum:“1”, recordId:“1”, suspect:“false”, value:“” }, { name:“FirstName”, childIdx:“1”, children:0, parentName:“Customer”, occurNum:“1”, value:“xyz1” }, { name:“MiddleName”, childIdx:“2”, children:0, parentName:“Customer”, occurNum:“1”, value:“pqr1” }, { name:“LastName”, childIdx:“3”, children:0, parentName:“Customer”, occurNum:“1”, value:“abc1” }, ]);

In the above array representation, the “root” corresponds to the root node 510, “customer” corresponds to a customer node 530, “FirstName” corresponds to a first name node 530A, “MiddleName” corresponds to a middle name node 530B, and “LastName” corresponds to a last name node 530C.

Once the array representations of the records 310(1-2) are generated, the Array Representation #2 of the non-reference record 310(2) is merged into the Array

Representation #1 of the reference record 310(1) to generate a merged array representation of the reference record 310(1), as presented below:

public var diffArr1:ArrayCollection = new ArrayCollection([ { name:“root”, childIdx:“0” children:1, parentName:“”, occurNum:“1”, parentName:“”, hidden:“”, masked:“”, value:“” }, { name:“Customer”, childIdx:“1”, children:3, comment:“”, duplicate:“true”, groupNum:“1”, hidden:“”, masked:“”, match_score:“”, parentName:“root”, occurNum:“1”, recordId:“1”, suspect:“false”, value:“” }, { name:“FirstName”, childIdx:“1”, children:0, parentName:“Customer”, occurNum:“1”, value:“xyz” }, { name:“MiddleName”, childIdx:“2”, children:0, parentName:“Customer”, occurNum:“1”, value:“_” }, { name:“LastName”, childIdx:“3”, children:0, parentName:“Customer”, occurNum:“1”, value:“abc” }, ]);

The merged array representation of the reference record 310(1) includes the field “middle name” that is missing in the array representation of the reference record 310(1). In one embodiment, while merging, the fields of the Array Representation #1 are compared to the fields of the Array Representation #2 to determine the fields missing in the Array Representation #1. For example, it may be determined that the Array Representation #2 has the field “middle name” that is missing in the Array Representation #1. The missing field is added as the blank field in the Array Representation #1 to generate the merged array representation of the reference record 340(1). The value of the blank field is blank. For example, as shown in the merged array representation, the value of the included field “middle name” is blank (underlined in above merged array representation).

Based upon the addition of the missing field (e.g., Middle name), the Childldx and the Children information in the merged array representation are updated. For example, as shown in the merged array representation of the reference record 310(1), the Childldx and the Children information are updated. The updated Childldx and the Children information are underlined in the above merged array representation for reference.

In one embodiment, the merge algorithm 400 may execute the following merge operations to merge the array representation of one record into another, e.g., to merge the Array Representation #2 (secondCardArray) into the Array Representation #1 (firstCardArray):

Merge Operation: MergeCard2IntoCard1 (firstCardArray, secondCardArray).

When the operation MergeCard2IntoCard1 (firstCardArray, secondCardArray) is executed, the secondCardArray (Array Representation #2) is merged into firstCardArray (Array Representation #1) to generate the merged array representation (MergedfirstCardArray) of the reference record 310(1).

The MergedfirstCardArray is merged into the secondCardArray (Array Representation #2) using the below merge operation to generate the merged array representation of the non-reference record 310(2).

Merge Operation: MergeCard2IntoCard1 (secondCardArray, MergedfirstCardArray).

Similarly, if there are three records (cards) the merge algorithm 400 may execute the merge operations (i) MergeCard2IntoCard1(firstCardArray, secondCardArray), (ii) MergeCard2IntoCard1(firstCardArray, thirdCardArray), (iii) MergeCard2IntoCard1(secondCardArray, MergedfirstCardArray), and (iv) MergeCard2IntoCard1(thirdCardArray, MergedfirstCardArray). The firstCardArray represents the array representation of the reference record, the secondCardArray represents the array representation of the non-reference record 1, the thirdCardArray represents the array representation of the non-reference record 2, and the MergedfirstCradArray represents the merged array representation of the reference record.

The array representation of the non-reference records (secondCardArray and thirdCardArray) are merged into the array representation of the reference record (firstCardArray) using the operation (i) and (ii). The merging results in generation of the merged array representation of the reference record (MergedfirstCardArray). The MergedfirstCardArray is then merged into the array representation of the non-reference records (secondCardArray and thirdCardArray), using the operations (iii) and (iv), to generate the respective merged array representation of the non-reference records. The merged array representation of the records (MergedfirstCardArray, MergedsecondCardArray, and MergedthirdCardArray) are aligned relative to each other.

In one embodiment, based upon the merged array representations of the records 310(1-N), the merged records 340(1-N) are generated. The merged records 340(1-N) may be in the XML format. In another embodiment, based upon the merged array representation of the records 310(1-N), the merged records 340(1-N) are generated in a suitable format that can be displayed on the UI 350.

The merged records 340(1-N) are displayed on the UI 350. The merged records 340(1-N) are displayed in the card view 360. In the card view 360, the merged records 340(1-N) are positioned side-by-side or adjacent to each other in a vertical arrangement. In one embodiment, the merged reference record 340(1) is displayed at an extreme left in the card view 360. In one embodiment, the merged master record may be displayed at the extreme left in the card view 360. For example, if the user selects the record 310(1) as the master record then the merged master record 340(1) may be displayed at the extreme left in the card view 360. The master record 310(1) is the record against which the other records 310(2-N) are required to be compared. In other embodiments, the left side is replaced with the right side.

While displaying the merged records 340(1-N) on the UI 350, the blank fields included due to merging are highlighted with a predefined color. If a plurality of consecutive blank fields are added as a result of merging then the consecutive blank fields are highlighted with a different shades of the predefined color. In one embodiment, the consecutive blank fields are highlighted such that alternate blank fields have a same shade of the predefined color.

The below paragraphs describe aligning two exemplary records and displaying the aligned records on the user interface 350. The exemplary records may be records 600A and 600B (illustrated in FIG. 6) that are required to be aligned. The record 600A being the reference record and the record 600B being the non-reference record. The non-reference record 600B is merged into the reference record 600A to generate the merged reference record 700 (FIG. 7). The merged reference record 700 is merged into the non-reference record 600B to generate the merged non-reference record 800 (FIG. 8). The merged records 700 and 800 are aligned relative to each other.

As shown in FIG. 7, the merged reference record 700 includes fields (620B, 620H1, 620H11, 620H12, 620H2, and 620H21) that are missing in the reference record 600A. The missing fields (620B, 620H1, 620H11, 620H12, 620H2, and 620H21) are included from the non-reference record 600B as blank fields. The blank fields (620B, 620H1, 620H11, 620H12, 620H2, and 620H21) are highlighted with a predetermined color while rendering the record 700 on the UI 350. Further, the plurality of consecutive blank fields 620H1, 620H11, 620H12, 620H2, and 620H21 (added as a result of merging) are highlighted with different shades of the predefined color while rendering the record 700 on the UI 350. The consecutive blank fields 620H1, 620H11, 620H12, 620H2, and 620H21 are highlighted such that the alternate blank fields (620H1, 620H12, and 620H21) or (620H11 and 620H2) have the same shade of the predefined color.

As illustrated in FIG. 8, the blank fields included due to merging (e.g., the fields 620H1, 620H11, 620H12, 620H2, and 620H21) in the record 700 are highlighted (illustrated as hashed fields and dotted fields). As the fields 620H1, 620H11, 620H12, 620H2, and 620H21 are consecutive fields, the fields are highlighted with different shades of the predefined color such that the alternate blank fields (620H1, 620H12, and 620h21) have the same shade of the predefined color (illustrated as dotted fields). Further, the alternate fields (620H11 and 620H2) have the same shade of the predefined color (illustrated as hashed fields).

Similarly, the fields included due to merging (e.g., the fields 610T, 610F, and 610E) in the record 800 are highlighted (illustrated as hashed fields and dotted fields). In one embodiment, the included blank fields 610T, 610F, and 610E are highlighted with the predefined color. As the fields 610T, 610F, and 610E are consecutive fields, the fields may be highlighted with different shades of the predefined color such that the alternate blank fields (610T and 610E) have same shade of the predefined color (illustrated as hashed fields in FIG. 8).

In one embodiment, the blank fields 620H1 and 620H2 may be included at new level of hierarchy. For example, the fields ‘620H1’ and ‘620H2’ added as blank fields due to merging creates new level of hierarchy in the record 700. As illustrated in FIG. 8, the fields 620H12 and 620H2 are included at the new or additional hierarchical level in the merged record 700. The additional level of hierarchy is displayed on the UI 350 with an empty branch icon 710(A-B). The empty branch icons 710A and 710B are expandable and collapsible. The empty branch icon 710(A-B) is expanded or collapsed to display or hide one or more fields included within the additional level of hierarchy. For example, the empty branch icon 710A may be collapsed to hide the fields 620H11 and 620H12 included within the additional level of hierarchy 620H1.

In one embodiment, the UI 350 includes several enhancements to enable the user to improve the reviewing and comparing task. For example, the UI 350 includes a title column 810 (FIG. 8) prefixed to the merged reference record 700 positioned at the extreme left. In another embodiment, the horizontal positions are reversed and the position is on the right. As illustrated, the title column 810 includes names (first name, middle name, last name, address, street, house number, etc) corresponding to each field of the displayed records (700 and 800). For example, the “first name” is displayed corresponding to the fields 610A and 620A of the displayed records 700 and 800.

In one embodiment, the UI 350 includes status columns corresponding to each displayed non-master records 340(2-N). The status columns may be prefixed to the respective records 340(2-N). For example, considering the reference record 700 as the master record, the UI 350 includes the status column 910 (FIG. 9) prefixed to the non-master record 800. The status column 910 includes status corresponding to each field of the non-master record 800. In one embodiment, the status column 910 includes a status icon to indicate ‘match’ or ‘no-match’ of the field value with the corresponding field value of the master record 700. For example, the status column 910 includes the icon ‘°’ to indicate ‘match’ and an icon ‘x’ to indicate ‘no-match,’ as illustrated in FIG. 9.

In one embodiment, the UI 350 includes a hide-and-show option (not shown). The hide-and-show option hides or shows a specified field or row corresponding to all the displayed records 340(1-N). In one embodiment, if any one of the displayed record is scrolled all other records are scrolled accordingly (i.e., synchronized scrolling). For example, if the record 340(1) is scrolled then all other displayed records 340(2-N) are also scrolled accordingly or concurrently. Similarly, if the field of any record, e.g., record 340(1), is selected then the corresponding fields of all other records, e.g., the records 340(2-N), are also selected automatically (i.e., synchronized selection).

In one embodiment, each displayed record 340(1-N) includes a drag-and-drop feature. The drag-and-drop feature enables the user to drag a field within the record. For example, the user may select the field ‘620C’ of the record 800 and drags the selected field ‘620C.’ The dragged field 620C is droppable within the same record 800 and on the same level of hierarchy from where the field 620C is dragged. For example, the field 620C may be dropped in position of 620B within the record 800. In one embodiment, if the user attempts to drop the field 620C on different level of hierarchy, e.g., on field 620H1, then either an error message is displayed or there is a failure in dropping the field.

In one embodiment, the resultant records 340(1-N) rendered on the UI 350 include the “match_score” field denoted the match score. For example, as illustrated in FIG. 9, the records 700 and 800 include the match score field 920A and 920B, respectively. The match_score 920(A-B) indicates a percentage of match of the record with the master record. For example, if the user selects the record 700 as the master record then the match_score 920B of the record 800 shows the percentage of match of the record 800 with the master record 700. In one embodiment, if the match score 920B of the record 800 is above a predefined maximum value (e.g., 90%), the record 800 is approved and is not required to be manually reviewed. In one embodiment, if the match_score 920B is below a predefined minimum value (e.g., 45%) the record 800 is discarded. In another embodiment, if the match_score 920B is in between the predefined minimum value and the predefined maximum value (e.g., in between 45% and 90%), the record 800 is a suspected record that is required to be reviewed manually. In yet another embodiment, the match_score 920A of the master record 700 may be empty (blank). In one embodiment, based upon the drag-and-drop operation, the match_score 920B of the non-master record 800 is updated. In another embodiment, the match_score 920B may be updated based upon triggering the hide and show option.

In one embodiment, the non-master records 340(2-N) includes a suspect flag. For example, the non-master record 800 includes a suspect flag 930. The suspect flag 930 indicates if the record 800 is a suspected record. In one embodiment, the record 800 is the suspected record if its match_score 930B is within a predefined range, e.g., more than the minimum predefined value and less than the maximum predefined value. The suspected record 800 is required to be reviewed. In another embodiment, a background of the suspected record may be highlighted with another predefined color (not illustrated) while displaying the record on the UI 350.

In one embodiment, if the merging is not performed successfully, the original records 310(1-N) are displayed on the UI 350 in the card view. If the merging is not performed successfully, the records 310(1-N) may be unaligned in the card view. In another embodiment, if the merging is not performed successfully, an error message may be displayed on the UI 350.

In one embodiment, the merged array representation includes some markers. A marker (e.g., a counter) may help in highlighting the fields while converting the array representation into the XML record. In another embodiment, the array representation may include the markers to indicate that the value of the field in the merged non-master record is different from the value of the corresponding field in the merged master record. If the value of the field in the merged non-master record is different from the value of the corresponding field in the merged master record, the field(s) of the merged non-master record may be highlighted with a specific predefined color while rendering the merged non-master record on the UI 350.

FIG. 10 is a flowchart illustrating a method for aligning the records 310(1-N) using the array representation of the records 310(1-N), according to an embodiment of the invention. The array generating algorithm 400 traverse each record 310(1-N) to generate the array representation of each record 310(1-N) at step 1001. The array representation of the reference record 310(1) and the non-reference records 310(2-N) are generated. The array representation of the one or more non-reference record 310(2-N) is merged into the array representation of the reference record 310(1) to generate the merged array representation of the reference record 310(1) at step 1002. In one embodiment, the array representation of each non-reference record 310(2-N) is merged into the array representation of the reference record 310(1) to generate the merged array representation of the reference record 310(1). The merged reference record 340(1) is merged into the array representation of each non-reference record to generate the merged array representation of respective non-reference records 310(2-N) at step 1003. Based upon the merged array representation of the reference record, the merged reference record 340(1) is generated at step 1004. Similarly, based upon the merged array representation of the non-reference records 310(2-N), the merged non-reference records 340(2-N) are generated at step 1005. The merged records 340(1-N) may be the XML formatted records. The merged records 340(1-N) are aligned relative to each other. The merged record 340(1-N) are displayed on the UI 350 in the card view at step 1006.

FIG. 11 is a flowchart illustrating a method for displaying records 310(1-N) based upon the merging operation. Once the merging operation is executed by the merge algorithm 330, it is determined if the merging is successful at step 1101. If the merging is unsuccessful (step 1101: NO), the original records 310(1-N) are displayed on the UI 350 in the card view at step 1102. The original records 310(1-N) may be misaligned. In one embodiment, if the merging is unsuccessful, the error message may be displayed on the UI 350. In case the merging is successful (step 1101: YES), the blank fields included due to merging are highlighted with the predefined color while rendering the merged record 340(1-N) on the UI 350 at step 1103. In one embodiment, if the merging is successful (step 1101: YES) it is determined if the plurality of consecutive blank fields are included due to merging at step 1104. In case the plurality of consecutive blank fields are included due to merging (step 1104: YES) the consecutive blank fields are highlighted with the different shades of the predefined color such that the alternate blank fields have the same shade of the predefined color at step 1105. The merged records 340(1-N) with highlighted fields are displayed on the UI 350 in the card view 360 at step 1106.

The embodiments described above provide techniques to align records. Filler rows (blank fields) are included or added in place of the missing data in each record to align the records relative to each other. The records are aligned such that the like data fields of the records line up in the same row. Further, rendering the aligned records in the card view enables a convenient and efficient comparison. Consequently, the user can perform a better visual scanning Moreover, the UI enhancements, e.g., the drag-and-drop feature, the background color highlighting, the status column, the title column, the suspect flag, etc., further improve the reviewing and comparing tasks. Additionally, the technique is flexible to adapt to various record formats and to any levels of hierarchy.
